Kubernetes & Containerization Security

Containerised Environments and Orchestration

Cloud-native architectures often rely on containerisation and orchestration platforms like Kubernetes. A compromised container could lead to further exploitation of the Kubernetes cluster, including testing namespace segregation boundaries, secret management, and lateral movement to other cloud resources. Our testing identifies vulnerabilities in these critical areas.

Secure Your Kubernetes Clusters Against Real-World Threats

Kubernetes has become the backbone of modern containerized applications, orchestrating workloads across diverse environments. However, vulnerabilities in Kubernetes clusters can lead to severe security breaches—including unauthorized access, data theft, and service disruptions. Our Kubernetes Security Assessment ensures your clusters are robust against these threats by thoroughly evaluating your configurations and deployments.

Leveraging our expertise and the latest security research, we go beyond standard benchmarks like the CIS Kubernetes Benchmark and the NSA-CISA Kubernetes Hardening Guidance. We blend these established frameworks with our hands-on experience to provide a dynamic and comprehensive assessment tailored to your unique environment.

What We Cover in a Kubernetes Security Assessment

Our Kubernetes Security Assessment encompasses a broad range of checks to ensure your clusters are secure and resilient. This includes testing the following.

• Role-Based Access Control (RBAC):  Ensuring users and services have the minimum necessary permissions.
• Network Policies: Verifying that network traffic is properly restricted and monitored.
• Pod Security Policies: Assessing the enforcement of security standards at the pod level.
• Secrets Management: We examine how sensitive data like passwords and tokens are managed. Ensuring secrets are encrypted and stored securely, and that only authorized authorised entities can access sensitive information.
• Workload Analysis: We analyse your deployed applications for potential security risks including identifying outdated or vulnerable container images and assess the security of workloads during execution.
• Network Security: We test your network policies and ingress/egress controls to prevent unauthorized access.
• Access Controls: Ensuring the API server is protected against unauthorized access.

Our assessments often uncover critical issues such as:

• Misconfigured RBAC Leading to Excessive Permissions: Users or services having more access than necessary.
• Inadequate Network Policies Allowing Unauthorized Access: Weak network restrictions that could lead to data breaches.
• Poor Secret Management Practices Exposing Sensitive Data: Improper handling of secrets that can be exploited.
• Use of Outdated or Vulnerable Container Images: Deployments using images with known vulnerabilities.

Real-World Attack Simulations

Evaluate Your Defences Under Real Attack Conditions

Our service doesn’t just highlight vulnerabilities, we can simulate realistic attack scenarios to demonstrate potential exploitation paths. By mimicking genuine threat actors, we assess whether malicious activities can be detected and thwarted, providing you with a clear picture of your security posture.

Working closely with your team, we define and execute an assessment tailored to your unique environment. This collaborative approach ensures we thoroughly test the real-world security of your Kubernetes clusters, leading to a deeper understanding of potential vulnerabilities.
